I have a little demo of this of my camera app:
https://shielded-plains-5586.herokuapp.com/
When you press "Drop', it creates a canvas after you take a picture with a webcam below it. My problem is that I don't know how to get the canvas into an image and have it save to my database through a form with paperclip on it. I'm really stumped. could anyone help?
Use canvas.toDataURL()
, will return the image data URI.
Post it to your server where you need to write the file and save the path in the database.
